Abstract:In this work, fundamental interactions in nanocellulose systems and their utility in fabricating novel and advanced cellulose-based materials was studied. More specifically two major aims were investigated. The first concentrates on cationic NFC and its morphology, its fundamental behavior with relation to charge and solvent, and its interactions with other nanocellulose particles. In the second, the approach focuses on the interfacial interactionbetween NFC and polymers (polysaccharides) to assess the importance of their mutual interplay on the mechanical performance of the nanocomposite films. Atomic force microscopy(AFM) in different imaging conditions (liquid and air, and different force detection modes) and the quartz crystal microbalance with dissipation (QCM-D), and tensile tests were combined to carry out this research.
